What happened to scott isnt murder. The criminal refuse orders to drop the weapon. He was shot. A consequence of refusing to follow orders. You have alot of options to engage suspects. Not very many when they are armed. The cops that shoot are being judge, jury and executioner, they shooting to protect their lives and possibly the lives of other people. If a person attacks you and you kill them, are you acting as their judge, jury and executioner, or are you just trying to protect yourself.
